摘要： Electromagnetic actuators are disclosed having at least one actively cooled coil assembly. Exemplary actuators are linear and planar motors of which the cooled coil assembly has a coil having first and second main surfaces. A respective thermally conductive cooling plate is in thermal contact with at least one main surface of the coil. Defined in or on each cooling plate is a coolant passageway that conducts a liquid coolant. A primary pattern of the coolant passageway is coextensive with at least part of the main surface of the coil. The primary pattern can have a secondary pattern through which coolant flows in a manner reducing eddy-current losses. An exemplary secondary pattern is serpentine. An exemplary primary pattern is radial or has a radial aspect, such as an X-shaped pattern. The devices exhibit reduced eddy-current drag.

摘要： A device comprising an energy selecting slit assembly is provided. The slit assembly comprising a slit assembly chassis, opposing slit mechanisms, and an actuator assembly. One of the terminal ends of the actuator arm comprises a relatively fixed terminus, while the other terminal end of the arm comprises a relatively mobile terminus coupled to the rotational slit mechanism via a mechanical coupling configured to translate movement of the mobile terminus into rotational of the rotational slit mechanism. In one embodiment of the present invention, the slit assembly chassis defines a plurality of fixturing datums configured to establish alignment of respective aperture-defining edges of the opposing slit mechanisms along orthogonal X, Y, and Z axes defined by the chassis. Additional embodiments are disclosed.
